Remember lubricating should be with an oil suitable for use with sinter-bronze. It needs to have the
right additives. Lubrication is done with the bearings submersed in the oil, while vacuum is pulled to get
the air out of the pores in the bearing metal. Then leave them submersed without vacuum for 24 hours to allow
oil to suck in.
If not oiled correctly the bearings will only run fine for a short time (hours or days).
Factory new bearings, pre-oiled and ready to fit is available from Danish Sound Parts.
I would recommend that as it also includes new reservoir felts and takes wear to the old bearings out of the equation.
